Open Access to ACM Digital Library During Coronavirus Pandemic

March 30, 2020

Dear ACM Members:

As the coronavirus/COVID-19 pandemic continues, we at ACM would like to do what we can to help support the computing community. Many computing researchers and practitioners are now working remotely. In addition, teaching and learning have also moved online as more and more campuses close.

We believe that ACM can help support research, discovery and learning during this time of crisis by opening theACM Digital Libraryto all. For the next three months, there will be no fees assessed for accessing or downloading work published by ACM. We hope this will help researchers, practitioners and students maintain access to our publications as well as increasing visibility and awareness of ACM’s journals, proceedings and magazines. Please be sure to inform your colleagues that the ACM DL is now open, and will continue that way through June 30, 2020.

This global health crisis is a unique challenge that has impacted many ACM members. We would like to express our concern and support for all who are affected by this outbreak.

Stay well!

Cherri Pancake
ACM President
